Q Can the meter s line voltage wires be run in the same conduit as the sensor leads A Yes there will be no effect on the meter if the sensor leads and line voltage wires are run in the same conduit Q Can the meter communication wires and line voltage wires be run in the same conduit A Itis NOT recommended to run these wires together due to noise concerns and their effects on the communications signal integrity Communication wires can be routed separately using the 1 2 conduit port How do find the cost for kWh and kW to bill my tenants A Your local utility bill should list the cost per kWh and kW If not simply call your utility and ask them to provide you with the cost per kWh and kW Q What size wire do use for the line voltage leads A These wires are normally 14 AWG but be sure to consult your local electrical codes for proper sizing requirements Q What size wire should use to extend the current sensor leads A These wires are normally sized at 14 22 AWG twisted pair arrangement Consult your local electrical codes for proper sizing requirements 31 62 0389 02 CLASS 2000 METER The load need to monitor has parallel feeds How do install the current sensors for this application A There are two ways you can monitor parallel feeds One method is to clamp the sensors around all feed wires for each phase no additional reading multiplier required The second way to monitor parallel
